My girlfriend used at home pregnancy tests and they came back positive. She was okay besides being tired and sore but her morning sickness started monday and it hasn't gotten any better. She can't eat at all and can't drink very much. She has a doctor's appointment friday but I'm worried about her and the baby since she can't eat and can drink very little. It never goes away,it's an all day thing and just the smell and/or sight of food will bother her. I know it's normal for a pregnant woman to have morning sickness and I know it can severe in some and bearable in others but I was wondering when is it that seeing a doctor about it necessary? She doesn't want to take anything OTC for the nausea because she's worried it'll hurt the baby(this is her first pregnancy).
